/**
 *      Model_Field types summary:
 *      - scalar: a scalar property value
 *      - Enumeration: a (statically or externally) predefined set of possible values,
 *          of which a property can have any (none to all)
 *      - OneToMany: a relationship to a dynamic set of values, i.e. another model's objects,
 *          of which a property can have any (none to all)
 *      - ForeignKey: a `belongs-to` relationship, i.e. there can be any number of objects of
 *          this model which reference some single object of another model
 *      - BelongsTo: same as ForeignKey, except the relationship is manipulated from the model
 *          this object belongs to (i.e. for this object the property is immutable once set; the
 *          referenced object can add to itself and delete from itself objects of this model)
 *      - ManyToMany: a relationship to another model, of which this object can reference any, and
 *          any number of this model's objects can reference same object.
 *      - SharedBy: same as ManyToMany, except the relationship is manipulated from the referenced model
